Acknowledged. The latest eldoc in master is a work in progress.This in on
my to-do list. Soon I'll improve the documentation, as well as specifying
what the "display engine" is supposed to be.

I think, this will be quite useful when (re) designing your eldoc-box
extension, Yuan. Maybe that extension could even be included into Emacs
itself.
